2 Claims.

My present invention relates to apparatus for I I washing dishes and themain objects thereof are the provision of improved apparatus for washingdishes; the provision of simplified apparatus for the cleaning of soileddishes; the provision of apparatus for the purpose stated which isinexpensive to manufacture and is eificient in use; and such furtherobjects, advantages, and capabilities as will hereinafter appear and asare inherent in the construction disclosed herein. My invention furtherresides in the combination, construction, and arrangement of partsillustrated in the accompanying drawings and, while I have shown thereinwhat is now regarded as the preferred embodiment of this invention, Idesire the same to be understood as illustrative only and not to beinterpreted in a limiting sense.

In the drawings annexed hereto and forming a part hereof,

Fig. 1 represents a horizontal section taken substantially along theplane indicated by the line I-I, Fig. 2;

Fig. 2 represents a vertical section with parts shown fragmentarily;

Fig. 3 represents a vertical section approximately along the planeindicated by the line 3-3, Fig. 1; and

Fig. 4 represents ,a broken vertical section taken substantially alongthe plane indicated by the line 4-4, Fig. 1.

Reference will now be made in greater detail to the annexed drawings fora more complete description of this invention. The working parts of thisconstruction are enclosed in a housing I and comprise the tub 2, themotor 3, and the pump 4. On the shaft of the motor there is a beltpulley 5 which is connected by a belt I to the pulley 6 mounted on theshaft 8 of the pump. On the inner end of this shaft 8 is an impeller 9which withdraws water from the tub 2 and forces it around the pipe II]and back into the tub 2 in a direction to engage the edges of plates,saucers, and the like, stood up in the basket II. As shown in thedrawings, the inlet end I2 of the fluid conduit is large and permitsfree access of water thereto, drawn in by the pump 9. The outlet end ofthe conduit I9 is elongated in a vertical direction but compressed in adirection at right angles thereto. Therefore, rotation of the impeller 9forces the washing fluid through the conduit at an increasing rate andout against the dishes with considerable velocity.

A second pulley, indicated at I3, is mounted on shaft 8 and is connectedto a pulley I4 by a belt I5. The pulley I4 is carried by a shaft I6which has a pinion II at its inner end. The pinion I'I cooperates with aring gear I8 on the under side of the basket I I in rotating the basketwhich is suspended on a plurality of pulleys I9 carried by the innerwall of the tub 2. The basket I I comprises a plurality of rings 20, 2|,22 to which are secured a plurality of outwardly extending wires 23.These wires are connected at their inner ends to a ring 25, comparableto rings 20, 2|, 22, From the rings 23 and 25 rise a series of wires 24.The upper ends of these upright wires are connected to a ring 26 whichforms an outside upper boundary of the basket. The upper outwardlyextending wires 23 are comparable to the lower wires of the basketwhich, together with the rings 20, 2|, 22 and 25, form compartments forthe reception of fiattish dishes, such as plates, saucers, and the like.Cups and other hollow ware can be placed on top of these upper wires 23,with their hollow sides facing the water stream so that they can bewashed by water forced against them.

At the center of the tub is a cup 21 in which is supported a wire screen21a having an opening facing the stream of water emerging from the pipeI 0 and striking the dishes in the basket II. The water which washesparticles of food from the dishes carries them into the screen 25 whichstrains them out of the water, allowing them to collect in the cup 21from which they may be removed. A valve controlled pipe 29 is providedfor withdrawing the wash water from the tub 2. The washed dishes may beput out on the draining board 28 from which the wash water runs backinto the tub 2. The tub 2 is shown as being provided with a cover 30.

Briefly stated, the operation of the machine is as follows. The dishesare placed in the basket II and hot water is put into the tub 2 until itcovers the exit from the tub into the pump. The motor is then startedand this drives the impeller 9, forcing the water out through the end ofthe water-carryingpipe I0 and against the dishes in the basket II. Thisbasket is rotated slowly by the pinion I'I driven indirectly from themotor 3. After the dishes are sufiiciently washed, the motor is stoppedand the dishes are removed from the basket and placed on the drainingboard.

It will of course be understood that the specific description ofstructure set forth herein may be departed from without departing fromthe spirit of this invention as set forth herein and in the annexedclaims.

Having now described my invention, I claim:

1. In a structure for the purpose stated, a fixed container for thereception of a washing fluid, spaced supporting rollers mounted thereinand adapted to rotate on their axes, free from contact with the bottomof the container, a basket supported on said rollers and adapted torotate in said container, mechanism for rotating said basket in saidcontainer, said basket having an un obstructed central opening, anon-rotatable netting trap for detached particles centrally located insaid container within said central opening and extending upwardlythrough said opening, and a pump having an inlet pipe and an outlet pipeconnected to the container at separated points to withdraw the washingfluid therefrom and return it thereto at a velocity at least as great asthe velocity of withdrawal, said trap having a longitudinally extendingslot in its wall facing the return end of the outlet pipe.

2. A washing machine comprising, in combination, a container forarticles to be washed, an article-holding basket supported therein forfree rotation on rotatable means, said basket having an unobstructedopening in the bottom thereof, a fixed screen extending upwardl from thebottom of the container through the opening in the bot tom of the basketand having a vertical longitudinal slot in the wall thereof, the basketbeing rotatable about the screen and being provided with compartmentsfor the reception of articles to be washed, said compartments beingarranged approximately tangentially to the outer surface of the screen,means for withdrawing washing fluid from the container and returning itthereto at a point along the lateral-wall of the container, remote, inthe direction of rotation of the basket, from the point of withdrawal,and means for causing operation of the withdrawing means, said lastnamed means also causing rotation of the basket about the screen, theslot in the screen facing the water-return opening.
